Defining And Analysing Emotional Labor Philosophy Essay

Defining And Analysing randy Labor Philosophy EssayEmotional travail is the control of a psyches behavior to display the appropriate emotions. This means that if a person wants to conform to social norms it will have to show authoritative emotions. The concept of stimulated labor affects every aspect of life. This paper will examine emotional labor in benefit industries.DefinitionArlie Hochschild defined for the low duration the term of emotional labor as the go away done with tactile propertys as paid employment. Hochschild pointed taboo that people control their emotions at work and in the private life. Whenever someone varys something in order to conform to an ideal, something that every human beingness does, it is emotional labor.Another definition comes from Chu and it says that emotional labor is the control of a persons behavior to display the appropriate emotions.For example, if you are a client service appointative, the 80th person asking the same question must be answered as thoroughly as you served the first person. Otherwise, you are not doing your business line of providing node service because that 80th person has no idea that youve answered the same question 50 meters. They just need an answer.The jobs requiring emotional labor are either face-to-face or have voice contact. It has been proved that people put up feel if the person at the other end of the line is smiling.Attitudes and behaviors at workAn individuals belief close to job, on the job(p) place or working team is shaped by emotions. Emotions affect behaviors at work. Research shows that individuals that are within your inner circle are better able to recognize and understand your emotions. The connection between emotions and emotional labor brush off be explained by the Affective Events Theory. Howard Weiss and Russell Cropanzano are the researchers that have studied the effect of six major emotions categories in the workplace. These are anger, fear, joy, love, dark ness and surprise.Their scheme states that specific regularts that take place in the workplace cause people to feel variant emotions. These emotions disregard be faithful for the job, for instance by exalt actions that can benefit others, but it could also be bad, by inspiring actions that could impede others. For example, imagine that a coworker un sojournedly delivers your coffee at work. As a result you whitethorn feel happy and surprised. If that coworker is your chieftain you would probably feel proud. Studies have found that positive emotions at the workplace may inspire you to do things that you hadnt planned to do before. Such things could be volunteering to help a colleague with a project. On the other side if you were unfairly treated by your boss you could take care negative emotions that could make you withdraw from work or act mean towards a colleague. Over time, these tiny moments of emotion on the job can influence a persons job satisfaction.Hochschilds types of emotional performingThere are three types of emotional acting lift acting, deep acting and genuine acting. wax acting is expressing an emotion without in truth feeling that emotion. This is the most stage businessed type of emotional acting in the workplace because it has the most side effects. Surface acting most often involves putting all the negative emotions, such(prenominal) as anger, annoyance, sadness, etc. behind and substitute them with positive emotions, such as happiness, excitement, care, etc. because the customers expect it. For example the stylist of a crying child cutting its hair off may smile and act sympathetic without actually feeling so. involved acting takes surface acting one step forward. This time, instead of faking an emotion because someone expects it, an employee will try to experience the emotions they are displaying. In the part of the hairdresser cutting the hair off a crying child, the hairdresser may empathize with the child by thinking what it s like to be in the childs shoes. In this case the hairdresser might understand that the child is scared being in an unfamiliar environment and the hairdresser may genuinely feel sad for the child.Genuine acting happens when individuals are asked to display emotions that are aligned with their own. If a job requires genuine acting less emotional labor is required because the actions represent the individuals true feelings.In conclusion, when it comes to acting the genuine your actions are the less emotional labor a job requires and the more your actions in the surface acting set off are the more emotional labor a job requires.The feeling rulesIn order to understand emotional labor we have to see what determines the fix emotional response to a situation. In Hochschilds book is being described a set of feeling rules, which Ashfort and Humphrey also called the display rules, rules that people use in order to identify what is the appropriate behavior. These feeling rules describe what the correct response for a work situation is and they can either be part of the job training or just manners. Most big companies usually have a set of policies that teach the employees how to conduct with customers. This case is about the written feeling rules.A good example for written feeling rules is McDonalds that encourages sincerity and enthusiasm but also a sense of humor in their service personnel. nevertheless most of the feeling rules are unwritten as in the case of manners. The feeling rules are also connected with the cultural background. For example if two managers from different cultures meet they both act correctly for their cultures point of view but they could very easily offend the other one accidentally. In the Australian work place people would generally be polite and show respect regardless of how the interlocutor reacts.The most evident moment when emotional labor occurs is when something goes molest and the customers are unhappy and dissatisfied for a numbe r of reasons. In most situations the employee should re of import calm and polite even if the customer irritates or upsets the employee, as the case of most situations. This is the form of self control and the feeling rules are very important in these situations because the employees know they must be polite.Ashforth and Humphrey define ten prop that include trustworthiness, courtesy, approachability and understanding, a set of feeling rules by which employees operate, whilst the customers expect good service. The expectation of each dimension changes with the customers moods. But it is also possible that the customer has expectations that are unreal and cannot be satisfied. In this situation even if the employee works gibe to the feeling rules, the customer would not be satisfied.Some service industries such as flight attendants, medical professionals or call center operators are the subject of higher expectations. These service industries are the ones that spend a set of time i nteracting with people. This interaction includes the customers expectation to good service. For example good service from a flight attendant includes politeness, a caring attitude and happiness. The feeling rules would have to change according to the age of the passengers. For instance, a flight attendant will have to behave differently to a child, a teenager, their grandparents, etc.People decide according to the feeling rules how to correct emotional response to a situation. But if something goes wrong in this system there are harmful consequences for the individual.The aims of emotional laborThe main aim of emotional labor is a positive affective display in service interactions, such as smiling, politeness, friendliness, which are positively associated with important customer outcomes, such as intention to return, intention to recommend a throw in to others and the image of overall service quality.Dealing with emotional laborAll service industries are connected to interaction w ith customers. These jobs require the employee to be nice and polite to the customer no matter how the customer treats him. This may speck in time to negative effects. Sandi Mann discusses in his book that having to manage your emotions in such way may lead to work stress. This stress may cause hypertension, heart diseases, even exacerbate cancer. This is because people usually tend to surface act. Surface acting can cause detachment from own emotions and individuals may suffer, as a result, burnout that may lead to dissatisfaction with the quality of work completed and doubt the effectiveness, this leading the sufferer to leave the job.So imagine the case of a stewardess. If care and friendliness is in all lost due to emotional stress, burnout or so on, the key element of the job will be gone and the customers expectations will not be met. As consequence, customers will not come back and they will probably not recommend the airline anymore.These serious side effects are most conc ern of human resource management. human resources can prevent this emotional cycle by using different methods in different situations.There is necessary to bring strategies in order to avoid problems with the employees. There are two types of strategies organizational and individual strategies.Organizational strategiesSome of the strategies that the management can use within a whole organization in order to reduce stress and therefore to avoid surface acting are as follows.First of all, the management can organize meetings with the employees to discuss the extent of stress and to find out if stress is widely spread in their company. Additionally, by debriefing the employees a company can prove for stress-causing factors and so, conduct a survey and inspect the workplace for stress causing factors.Another important aspect is to alter communication by hiring instruct professionals or supervisors for the employees to talk to when they experience negative events so that they can rec eive advice to identify surface acting and receive good feeling rules by which to operate. as well in order to help the employees a company can use hotlines where the employees can call if they have problems.A company can also improve job and organizational design in order to prevent stress-causing factors. For instance, a company can offer babysitters, cooking courses so that all the employees could come unitedly and have some fun.Individual strategiesThere are also strategies for individuals, especially because employees tend to stress themselves out. To avoid this, they can do some physical exercises, in order to be active and to reduce stress symptoms. Also, hobbies are very good to find relaxation and amusement.Additionally meditation is a good lance to gain inner peace and harmony, two basic elements for protection against stress.To conclude, an assertiveness training gives the employee the chance to develop self-confidence and self-awareness so that the employees are able to rig themselves and to become accepted in the working group.In order to apply everything stated in this paper we decided to take the example of emotional labor and Santa Clause.Christmas exemplifies consumerism in western society and it is a period of traditional ritual activities. All over the world Christmas themed services tend to encourage fantasy that lead to enjoyment of the customer. The center of the store has the purpose to enhance the buying experience and increase the probability of purchase. The provision of a warm, emotional delivery by an employee, as observed by Sutton and Rafaeli, promotes sales when customers expect to receive such individual friendliness. Therefore in order for the customers to feel good, the presence of Santa Clause in the store becomes a seasonal public relations addition for the image of a shopping center.Santa is a specialist public relations agent whose image relates to good looks, good sounds and good character. For children and adults, a visit to Santa is part of the Christmas ritual. A Santa interacts with individuals and in his work he has to deliver a personal performance of generosity and happiness. In order to be a Santa Clause people usually have to attend a Santa School. In this school the actors will learn some rules about how to be a Santa. One of the most important rules a Santa has to know is that he is not allowed to talk about politics, religion and life. In the Santa School the personality, experience and values of the actor are being mediated. This is because a Santa usually gets visited by all sorts of persons.Each visit is unique and the Santa needs to know how to handle it. He also requires independence of thought and action in order to be able to address to all possible variations of topics and ages of the visitors. In addition, a Santa also learns that he is not allowed to make promises and must know the attributes of all current popular toys so that he can look authentic.When Santa actors are co mfortable with their roles, the case of volunteering being a Santa, it takes very little effort to shape feelings as they are similar with their own feeling. But nowadays there are a lot of people that must do this job in order to get paid. So the people that havent asked to do this job. And to those people the emotional labor required is huge. They incessantly have to put a smiley face and be nice, because most of the visitors are children and they can get hurt very fast. So applying a part of the things that weve pointed out in our paper would probably motivate the Santa employee and makes this job easier.ConclusionEmotional labor is the control of ones behavior to display appropriate emotions. Feeling rules help to head for the hills it.Surface acting happens when an individual has to fake emotions leading to health issues, such as frustration, burn-out, depression or emotional exhaustion. Deep acting happens when an individual actually feels that emotion.Human Resources Manage ment can prevent these problems by using different strategies such as employing trained professionals or supervisors. It must be pointed out that Human Resource Management has to make emotional labor to a source of job satisfaction and to enable the employees to act deeper.All in all we hope that everyone in the sphere of action should deeply think about their own behavior and reactions in order develop self-awareness, and further to develop social awareness, so that individuals can become aware of others needs and wants.To sum it up it is a big problem for the management to deal with emotional labor because for one working in a company and doing the same thing every day it will end up feeling like a routine that leads to surface acting.

Air pollution control residues

carriage pollution control residuesINTRODUCTIONDescription of Overall ProblemAir befoulment Control ( armored personnel carrier) residues argon the solid output of the flue grease-gun interposition equipment installed on incinerators (this report refers specifically to armoured personnel carrier Residues from incinerators handling Municipal Solid be adrift MSW). They comprise the disappear ash from incineration (middle and fine grades) together with the reagents (mainly lime and activated carbon) used in the flue gas treatment. Thus, they containVolatile contaminants from the original neutralize (inc chlorides, metallic elements),Compounds created in the incineration work (inc dioxins), unless materials from the flue-gas treatment operation (sulphates, together with high alkalinity).Therefore they atomic number 18 sort as hazardous harry.Approximately 170,000t/y (Technology system Board 2009) of such residues argon produced in the UK 3-4% of the total ache mass inci nerated (Environment Agency, 2002). This tonnage is growing as more waste is incinerated to generate electricity and heat, and to quash landfill. While increased animation retrieval and trimd landfill ar worthwhile in themselves, achieving them has created the problem of the hazardous armored personnel carrier residues. In the UK the prevalent destination for these residues has been landfill, scarce this option is under threat from tightening landfill abandon betrothal Criteria, and rising landfill taxes, so new solutions ar required.There ar various treatment/recovery options operational for armored personnel carrier residues. However these raise other concerns, primarilyFinancial and energy cost of treatmentGeneration of further effluentEnvironmental tint of the treated wasteQuality control of the recovered materials.Objectives and ScopeThe overall goal is to identify cost-effective management options for armored personnel carrier residues, within Waste Acceptance Cr iteria. The ultimate objectives of implementing such options are shown in Requirements (Appendix 1). For this study, the specific the objectives areBriefly analyse the shortcomings of the existing methods of treatment and disposal of APC residue in landfills, a dour with the barriers in the UK for re-use of APC residues in various industries, such as cement aggregate, asphalt and ceramics.Propose energy- and cost-effective methods for the treatment of APC residue which let down the leach cleverness and tot up of heavy metal/dioxins shew. Also suggest a supplier of technology for each treatment method proposed.Compare the cost per tonne for each option, including treatment and disposal costs (including current and future landfill taxes), establish on the hazardous sort of any sticking waste.Suggest latent re-use opportunities for materials recovered from the treatment process, indicating potential markets and revenues.The scope is focused on APC residues from municipal waste i ncineration. It is assumed that current incineration technology and operating conditions apply, with waste of current composition, resulting in residues of current composition. The objectives reserve been pursued in the context of current UK and EU regulation. This is explained in terms of the waste management hierarchy in table 1.Notes of interpret 1Further processing leading to recovery may be in or outside the system boundary depending on whether the process is standardisedly to be utilize to this application. In either baptistry the resulting wastestreams are inside the system boundaryLandfill operations are outside the system boundary, but the long term leach behaviour of all landfill waste will be considered, even if it carry outs WAC.Report structureThis report has been structured to give an overall review of the management options for the Air Pollution Control residue, intended to provide a details of the findings related with work guideing to give recommendations on its treatment.Chapter 1.

Press Release is placed in Appendix 3 and this would form a basis of a universality campaign for the project.MANAGEMENT AND REGULATORY FRAMEWORK FOR APC RESIDUEAPC residues generation and characteristicsAPC residues come from the cleaning process of the gaseous emissions, which are produced during the incineration. Dry and semi-dry scrubber systems are used in the cleaning process and involve the injection of an alkaline material to remove acrimonious gases, particulates and flue gas condensation (Sabbas et al. 2003). Finally, fabric filters in baghouses are used, where the fine particulates, i.e. the APC residues are focalized and removed from the gaseous emissions (Sabbas et al. 2003). It is estimated that APC residues represent 2-5% of the original waste on a wet basis and their production in the UK is approximately 128,000 tonnes per annum (Amutha Rani et al., 2008). In general, APC residues from municipal solid waste incineration (MSWI) consist of fly ash, carbon and lime and contain dioxins and furans (Amutha Rani et al., 2008). They are highly alkaline materials (pH 12.0-12.6) and they comprise significant concentration of heavy metals, salts and micro-pollutants (Sabbas et al. 2003). Depending on the initial waste composition, the incinerator and the mien pollution control system, their composition may vary significantly (Amutha Rani et al., 2008). The typical range of APC residues composition is shown in table 2.The APC residues are characterized as hazardous wastes (190107*, according to the EWC) due to their chemical cognitive content and their impact on the environment, primarily by leach.Regulatory manikinIntroductionRegulations and code on waste management in the UK have evolved considerably over the years as a result of identification of new pollutants, public health and environmental concerns, economics and technological advancement (Pocklington, 1997 and McDougall et al, 2001). This assertion suggests that legislation and regulations play a major role in ensuring sustainable waste management. In addition, the establishment of legislation on waste management shows the radically changing perception of humans and communities towards the environmental impact of human activities (Pocklington, 1997). Today, regulations and legislation provide a framework for expeditious handling of hazardous wastes such as APC residue. Amutha Rani et al (2008) observed that sustainable management of APC residues depend on the implementation of UK and EU waste management legislation.The Existing regulatory and legislative framework for managing APC residues in the UKAbout 80% of the environmental legislation in the UK have their origins in the European Commission laws (Pocklington, 1997). The existing legislative and regulatory framework for APC waste management in the UK and EU implicateWaste Incineration Directive integrated Pollution Control DirectiveLandfill Directi ve and ensuing waste word meaning criteria/procedureEA guidance on the classification of hazardous wasteWater Framework DirectiveHowever, the discussion on the regulatory and legislative framework for this project focuses mainly on the UK Landfill directive and EA guidance on classification of hazardous wastes. These subjects are pertinent within the boundary of this project more so as Landfill disposal is common in the UK. Also IPPC directive is discussed briefly to highlight the roles public participation and deployment of best available techniques in meeting our objectives.The key objectives of these legislation and regulation are toReduce the amount of APC residue generated and improving the character of exhaust gas (McDougall et al, 2001)Reduce the amount of APC going to Landfill (EA Guidance on landfill, 2006)Prevent environmental impact (ESA 2004)Reduce the risk of human reproach (US National Research Council 2000, ESA 2004)This diagram illustrates the relationships betwe en the established regulatory framework and stages in the APC management process. There is no specific legislation cover charge recovery or reclassification of APC residue in the UK (ESA 2004). Quina et al (2008) also points out that legislation for recycling APC has not yet been established in the UK.The Integrated Pollution Control Directive Directive 2008/1/EC concerning integrated pollution foreseeion and controlThis Directive aims at establishing means to prevent or reduce emissions into air, pee and land (IPPC, 2008). Hence this directive is crucial as it suggests various methods of incineration and treatment that could reduce the impact of APC residues on the environment during incineration, treatment or landfill. The IPPC Directive is based on four principles namelyBest on hand(predicate) Technique (BAT)Integrated waste managementFlexibility macrocosm participationThe BAT refers to the nigh effective methods of operation that would reduce environmental impact and enhanc e results such as making residues from incineration less hazardous. In the BAT, optimizing resources and harnessing or saving energy are prioritized (Gargulas N. and Mentzis A, 2007). Also, the BAT is flexible and no terms are imposed since it recognizes that different conditions apply in different cases. The Best Available Techniques Reference (BREF) is a reference document on technical input needed to jell the BAT to be adopted. This BREF contains technical information on available means of treating APC residues such as sintering, vitrification, stabilization and solidification. This project has considered the daft to APC treatment and these methods are discussed in chapter 3. However, there are no BATs available for landfills. Notwithstanding, Landfill manipulators and APC treatment plants require permits issued by the Environment Agency with public support to ensure that there are no health or environmental impacts as a result of their activities (Macleod C. et al 2006 and IP PC 2008).The role of the public is crucial in this directive. Article 15 of the Directive, gives the public full privileges to participate in decision making processes leading to the issuance of permits for installation of plants, and for carrying out technical and administrative changes. This aspect is very important especially in the proper project planning and execution (see SEMP). Therefore the installations of APC treatment facilities and the method involved are tailored to meet public requirements as well as legislative requirements. All hazards inherent in operating APC treatment facilities shall be made known to the public in accordance to this directive. Also the outcome of conformation tests on treatment facilities with regard to environmental impact shall be made public (IPPC 2008). Thus, it can be argued that since the public are key stakeholders in this project, computable public perception is needed in accordance with the IPPC directive to ensure sustainable manageme nt of APC residues.Environment Agency guidance on classification of hazardous wasteThe essence of this guidance is to distinguish different kinds of wastes based on their physical and chemical properties which include their toxicity or hazardous nature.The unwarranted Waste Directive (HWD), council directive 91/689/EC and the Revised European Waste Catalogue (EWC) form the regulatory framework for this guidance. The HWD aims at defining hazardous wastes to ensure the correct management and regulation of such waste (EA Hazardous Waste 2008, pg 5). This directive identifies 14 hazardous properties of wastes, thus hazardous wastes are classified H1 H14 according to their hazardous properties (EA, Hazardous waste 2008). The EWC code is derived from the industry and process producing the waste, and the type of waste (EA hazardous waste 2008).APC residues are categorized as hazardous wastes with absolute entry (Rani et al 2008 and ESA 2004). Under the European Waste Catalogue (EWC), APC residues fall under the category of wastes from incinerators (waste management facilities) that have a generic code 19. The specific code for solid wastes generated from gas treatment such as APC residues is 19 01 07.Wastes resulting from the treatment of the APC residues such as the partially stabilized APC residue, the vitrified material etc are also categorized as hazardous with absolute entry (EA hazardous waste 2008). However, when tests prove that the constituents of treated waste have become less or non hazardous, they can be reclassified as hazardous wastes with mirror entry or non-hazardous as the case may be(EA Hazardous waste 2008). Solidified and partly stabilized wastes are coded 19 03 06 and 19 06 04 respectively with absolute entries, while vitrified wastes from flue gas treatment are assigned the code 19 04 02.The Landfill Directive 1999/31/EC of 26 April 1999 on the landfill of wasteThe primary objectives of the landfill directive areTo reduce waste going to landf illthe prevent or minimize environmental impact as a result of waste disposalStringent measures and standards have been even up to reduce the burden and reliance on landfill (EA guidance on landfill, 2006).Landfills are classified into three categories non-hazardous, inert and hazardous landfills (Landfill (England and Wales) Regulations, 2002)For APC residues, a key requirement in the Directive prior to landfill is to perform tests to determine its long term and short term leaching behaviour and to carry out treatment to reduce its toxicity (EA guidance on landfill, 2006). This project suggests that the need for treatment of APC residues augments the case for exploring potentials for recovery or reclassification of the residues.Article 6 c (iii) of the Directive reflects our aim to make APC residues at least stable non-reactive hazardous wastes (SNRHW) or completely non-hazardous through efficient treatment techniques such as vitrification, wash drawing, stabilization and germ p lasm technology. SNRHW are known to have low leaching potentials (EA guidance on landfill, 2006). Treated APC residues with leaching behaviour equivalent to those of non-hazardous waste can be disposed at designated non-hazardous landfill subject to meeting the relevant waste sufferance criteria (EA guidance on landfill, 2006 and Landfill (England and Wales) Regulation, 2002).APC residues must meet the waste acceptance criteria (WAC) for a designated landfill after treatment. Schedule 1 of the Landfill (England and Wales) (Amendment) Regulation 2004, stipulates the procedure and criteria for disposing or accepting waste at landfills.Waste Acceptance Criteria and ProcedureThe WAC is elaborately designed to exact with the technical requirement of wastes such as APC residues designated for landfills in the UK (England and Wales). It also aims at controlling the disposal of wastes into landfill which is a common practice in the UK. Technically, the WAC ensures that the numeric leachin g characteristics of APC residue are determined prior to disposal at landfill (EA Guidance on Landfill 2006). Thus, after their mandatory treatment, APC residues must meet the relevant waste acceptance criteria in the lead they are accepted into landfill. The leaching characteristics include the elements and compounds in APC residue and their leaching properties (in mg/kg or L/S) and the hazardous nature of the APC residue (EA Guidance on Landfill, 2006). The Environment agency is responsible towards ensuring that the criteria for detail landfills are met. Preceding the WAC is the Waste acceptance procedure.The Waste acceptance procedure for APC requires basic characterization, compliance testing and on-site verification (EA Guidance on Landfill 2006). The basic characterization is done to determine the physical and chemical characteristics of the waste (EA Guidance on Landfill 2006). Incineration plants are responsible for carrying out the basic characterization of the APC residu es since they produce the APC while the landfill operator ensures that compliance testing and on-site verification are done (EA Guidance 2006). Approved tests are defined in schedule1 part 2 of the landfill regulation 2004 and they include tests for determining treated APC composition and leaching behaviour. The compliance tests are carried out to verify if leaching limit levels predicted in the basic characterization are credible.Besides exploring opportunities for reuse of APC residues and recovery of valuable materials from the residues, this project also aims to treat APC residues to meet at least the waste acceptance criteria for SNRHW to enable disposal at a non-hazardous landfill. Amendment 14 of the Landfill (England and Wales) regulation 2004 states the criteria for disposing SNRHW in the non-hazardous landfill.DiscussionsThere is no specific legislation on the reuse of wastes such as the APC residues in the UK. Notwithstanding, the UK without incineration network (www.ukwi n.org.uk) tagged the use of fly ash and APC residues for construction works as irresponsible. Thus it can be suggested that re-use is implied in this article as well. However, if it is well proven that APC residues can be managed sustainably without any long or short term environmental repercussions, it will pave commission for debates to strengthen the existing regulatory frame and also re-focus the views of environmental activists toward the prospects in the residues.ESA report (2004) argues the provision of regulatory certainty by the government is necessary in enhancing investment towards sustainable management of APC residues. The report also suggests that investments will focus on reliable APC treatment technologies. There are several(prenominal) scientific developments for managing APC residues pioneered by waste management companies such as Techtronic in the UK.Environmental problems and management strategiesMost of the APC residues (around 88%) (Environmental Agency, 2002) produced in the UK, are disposed of into landfills. During their disposal or any kind of utilization or handling, a number of environmental impacts can be caused. pitter-patter and Gas emissionsDust emissions are represented as a potential risk, due to the size of the APC residues particles (0.001-1 mm) (Sabbas et al., 2003). Despite the easily dispersion of these fine particles, a survey by the Environmental Agency at a number of landfill sites in the UK testifies that their concentrations are within the recommended air quality objectives (Environmental Agency, 2002).Gas production is another potential environmental impact related to the disposal of APC residues. Gas is produced by metallic aluminum hydration (Sabbas et al., 2003) and because of that, some explosions have been reported (Sabbas et al., 2003). However, the production of gas is significantly trim compared to the production of the municipal solid waste landfills, due to their low biodegradable content of the APC resi dues.Leaching productionThe major environmental impact is the leaching production of APC residues The leaching behaviour of the elements present in APC residues is the main source of environmental concern. Leachates can cause pollution of soil, groundwater and surface water bodies. The leaching behavior of the APC residues is very complex and depends on a lot of arguments. The pH and the liquid to solid (L/S) ratio of the residues that will occur in the landfill site are important factors which affect determine their leaching behaviorbehaviour as well as the availability of the elements which are contained in the APC residues.The pH depends on the characteristics of the leaching fluid and the waste, i.e. APC residues, and is the key factor of many elements leachability. Leaching of most major elements (e.g. Al, Ca, S, Mg) and heavy metals (e.g. Cd, Pb, Zn) are strongly pH-dependent (Astrup et al., 2006). This dependency of the pH causes a significant difficulty on the prediction of the leaching behaviorbehaviour. Generally, APC residues carry on their pH in alkaline values for a long cartridge clip (many thousands of years) (Astrup et al., 2006). However, their pH decreases as the time passes and the APC residues are washed by the infiltrating water (the neutralize capacity decreases) (Astrup et al., 2006). Thus, the prediction of the landfills pH and thereby the leaching behaviorbehaviour of the residues in over a long term period is complex.The L/S ratio represents the amount of the leachate that comes in contact with a given amount of APC residues (Sabbas et al. 2003 pp what page?) and depends on the characteristics of the APC residues and the climatic conditions, the hydrology and the hydrogeology of the area (Sabbas et al. 2003). Usually, as the time of disposal passes the value of the L/S ratio becomes higher for a particular application site. Due to this contact the properties of the waste as well as the leaching behaviorbehaviour of the waste change. Thus, the value of this ratio is a very important parameter for the leachate content.The availability for leaching is a parameter, which characterizes the particular waste and represents a fraction of the total content of contaminants in the waste itself (Sabbas et al. 2003). The typical values of the availability for the APC residues are shown in table 2 and they can provide a theoretical estimation of the maximum release of a contaminant in a period of 1000 to 10000 years (Sabbas et al. 2003).The prediction of the leaching behaviour and the evaluation of the environmental impact of APC residues are based on leaching tests. Leaching values for the APC residues arising from leaching test are summarized in table 4.The first leachate from APC residues is usually characterized from soluble salts (e.g. chlorides, hydroxides of calcium, sodium and potassium) and trace element such as Pb and Mo (Sabbas et al., 2003). Contrary to the high solubility of this elements, the solubility of tox ic organic compounds is believed to be not high due to their aquaphobic nature and their low concentration in APC residues (from properly operated MSWI plants) (Sabbas et al., 2003).Long term leachate concentrations are usually lower than the initial or they may remain atto the same level. The only exceptions are the elements Al and Zn, which concentrations in the leachate are increase d inover a long term period (Astrup et al., 2006).As it is explained above the leaching behaviour of the APC residues depends on the environmental conditions and changes during the time of the disposal. Thus, an analytical prediction of the long term leaching behaviour is very difficult and it should be based on a combination of information on leaching principles, leaching tests, field measurements, simulation of mineral changes and speciation (Sabbas et al., 2003 page number pls). Due to the complexity of the long term leaching behaviour, the data available in literature are limited.Management of APC residuesIn the UK the disposal of any waste to landfill is regulated (see regulations section). Generally, the landfills are classified as suitable for hazardous, non-hazardous or inter wastes and, for each of these types of landfill, particular leaching limit values (Waste acceptance criteria, WAC) are defined and should be achieved for any waste are to be landfilled. Table 5 shows the leaching limit values (WAC) for the three types of landfill sites and if they are compared with the values in table 4, it becomes obvious that APC residues cannot be landfilled without a prior treatment.And non-hazardous waste deposited in the same cell.Either TOC or LOI must be used for hazardous wastes.UK PAH limit values are under development.Following the recent consultation exercise the UK Govt may review the limit values in tow years time (2006).If an inert waste does not meet the SO4 at L/S 10 limit, alternative limit values of 1500 mg/l SO4 at C2 (initial eluate from the percolation test) pr EN 14,405 and 6000 mg/kg SO4 at L/S10 (either from percolation test or bach test BS EN 12457-3), can be used to demonstrate compliance with the acceptance criteria for inert wastes.The values for TDS can be used instead of the values for Cl and SO4.Or DOC at pH 7.5-8.0 and L/S 10 can be determined on pr EN 14429 (pH dependent test) eluates.Disposal to landfill (Amutha Rani et al., 2008)APC residues are mixed with wastewater to form a solidified product. During this treatment the residues react with the CO2 from the atmosphere reducing the pH to values between 8 and 9. This mixing also eliminates the dispersion of the APC residues particles. by and by this treatment, the APC residues reach the WAC and they are landfilled into monofill cells at a hazardous waste landfill. This process is used by a treatment plant in GloucesstershireGloucestershire, from which most of the APC residues treated by this method in the UK are coming. Storage in salt minesIn this disposal method the APC res idues are ladened in sealed capsules and pitted 170m below the surface (Amutha Rani et al., 2008). The disposal in salt mines can take place for a long term. They are characterized as well isolated, very dry, with stable atmosphere and natural gas-impermeable salt layers (Clement, 2000). Salt mine for this purpose is located in Cheshire, England, where a major fortune of the APC residues, produced in the UK, are stored (Amutha Rani et al., 2008).Use in waste acid treatment (Amutha Rani et al., 2008)Due to the mixing of waste acid (usually HCl) and APC residues, the lime content of the APC residues is convertedsed into less hazardous components (CaCl2) and the concentrations of Zn and Pb are reduced. Furthermore, the pH is at high levels, preventing the salts release. Thus, the final mixture from this process is non-hazardous and it is draw as sludge from a physico/chemical treatment it is classified as EWC code 190206 and can be disposed of in non-hazardous landfills.TREATMENT TE CHNIQUESAsh race ProcessDescriptionThe objective of Ash washing process is to extract a number of minerals from the APC residue obtained after Municipal Solid Waste incineration and thereby diminish the leachability of various compounds remaining in the residue. The process also aims to improve the quality of the residue obtained for further re-use applications or to reduce the overall content of waste going to the landfill. According to Quina et al (2001), ash washing, acid leaching, electro-chemical process and thermal treatment are some of the most widely used methods for extracting metal values from the APC residues.The separation techniques studied in this section are ash washing with MgSO4, bioleaching using Asphergillus niger fungi and leaching using extracting agents. Each process has different prerequisites, operation time and cost, objectives and risks associated with them.Ash Washing With MgSO4Chimenos et al (2005)The process aims to apply the optimum parameters for wash ing APC residue by utilising minimum energy and water. This process uses multi-stage washing process to diminish the leaching of chloride and sulphate salts present in APC residue and thereby ensuring that the amount of harmful substance present in wastewater is reduced. The wastewater produced is recycled and re-used in the process using employing a rapid spray evaporation technique which runs on the waste heat produced from pumps, turbines and incineration furnace. Figure 3a showsrepresent the overall process diagram of operation.The research conducted by Zhang et al (2008) shows that the leachability of the heavy metals and chlorides present in APC residue depends on its pH level. The pH of the solution, when MgSO4 is added during the washing process, may be controlled by the formation of gypsum as shown in Eq(1).Ca(OH)2 + MgSO4 CaSO4 + Mg(OH)2..(1)BioleachingQ.Wang et al (2009)This process is considered to be a biohydrometallurgical approach to extract heavy metals from APC resi due. It is considered to be a green technology because of it makes use of the natural ability of microorganisms to break down solid compounds into soluble and extractable form by enzymatic oxidation or reduction. The process uses the acids secreted by Aspergillus niger fungi such as oxalic acid, citric acid and gluconic acids to extract the heavy metals present. Water-washing was is used as a pre-treatment before the bioleaching process to reduce the bio-leaching period from 30 to 20 days and to extract the maximum amount of chloride and sulphate salts. Figure 4 shows an overall process diagram for the bioleaching process. Bioleaching is a low cost and low energy consumption approach.Leaching Using Extracting AgentsFedje et al (2010)This process uses leaching agents other than water for extracting heavy metals like Zn and Pb. The efficiency of the extraction agent depends on heavy metals of interest, the concentration of the extracting solution, the pH and the liquid/Solid ratio use d. The goal of the process is obtain a solution in which the concentrations are high enough to enable further separation or recovery.The leaching media used for this process are3M HNO3 L/S = 50.1 M EDTA with pH adjustment L/S = 53M NH4NO3 L/S = 5The choice of these leaching media was based on their ability to form a complex with metal ions. Table 6 compares the efficiency of the aforementioned leaching agent in extracting the heavy metals from APC residue. Figure 5 represents the overall process diagram.The most widespread leaching method used for APC residues is acidic leaching using strong mineral acids such as HCl and H2SO4. However, due to the high alkalinity of APC residues, large amounts of acids are needed which results in trouble with storage and handling.Moreover, the reaction of APC resid

Coaches and Players Relationships Essay -- essays research papers fc

FindingsAfter reading these three articles between how preparees and workers do not get along with them attacking each other and when a recreateer does something terrible and the coach defends them. We all start been in a situation where we do not want to be talked to by a family member or friend just because he had a hazardous sidereal day, but when you bring that military capability to a sporting event or practice sometimes the player or coach my lose their composure. Which happened in the three articles that I read, dealing with Latrell Sprewell choked his coach PJ Carlesimo during practice, coach Bobby Knight choked one of his own players Neil Reed, and when Rick Carlisle defended Ron Artest and other players he coached after the brawl in Detroit. In reading those articles I spirit that they told me that in that respect is either a bad, matched, or good relationship between a player and coach. The one with Sprewell and Carlesimo, Sprewell who showed up to practice lat e that day choked his coach Carlesimo because Carlesimo wanted to know where he has been for being late. Although in the article it states that racial comments were said to Sprewell, but later found out that there were no such thing. So Sprewell was fired by the Golden State Warriors, the team he played for at the time, and was suspended by the NBA for the remainder of the season. In the article about Bobby Knight choking his player Neil Reed, it was halftime during a game when Bobby Knight was still coaching the Indiana Universitys mens basketball team and Knight was so upset with his players that the one player Neil Reed said something to Knight and Knight went after him and started choking him. After the news bust out about that incident the Indiana Universitys President fined Bobby Knight $30,000 and suspended him three games. In the final article I read coach Rick Carlisle defends Ron Artests actions against the Detroit Pistons fan that threw a cup of beer at him and then Art est went after him in that brawl we all heard about. It states that Carlisle feels that Ron Artest is a great player that he should be getting more respect from coaches, players, and fans but hes not because of his actions on and off the court. Rick Carlisle and Ron Artest though had a bad starting to this year when Artest asked for time off to promote his new album coming out. With that knowledge Rick Carlisle still d... ...s I stated before I am a coach, and after reading these articles I have definitely learned a lot from all these incidents and situations. Coaches and players need to establish a friendly, competitive relationship. What I mean by that is that when you are off the field or court you can be friends, you know joke with each other and have a good time, but when you get onto that field or court it is time to go to work and that playtime is over and you need to get heartrending to help your team and teammates compete at a high level of competition. If you do not have this kind of relationship with your coaches and players then I feel that your season as a team will become a total disaster, because you probably cannot trust each other when you go out to play the game. So thats why I feel that the coach, player relationship will help out or not a team in their season of play.BibliographyFreinstein, John. A Season on the Brink.

The Costs of Racism Essay -- Essays Papers

The Costs of Racism The Merriam-Webster Online Dictionary defines racism as a belief that race is the primary determining(prenominal) of human traits and capacities and that racial differences produce an inherent superiority of a particular race. Racism is one of the deepest stains on the pages of American history. What began as feelings among whites of being superior to blacks dark into possibly the worst phenomenon the United States ever dealt with. Even 100 years after Abraham Lincoln signed the Emancipation Proclamation, many white populate were appease treating blacks atrociously. It took many decades before blacks were granted truly equal rights that white Americans were given. In Anne drears autobiography, Coming of Age in Mississippi, she discusses growing up in Mississippi. She writes about her memories of childhood, high school, college, and finally her courageous work in the civil rights movement during the 1960s. heavy offers readers a startling and remar kable story of her life. She also gives outstanding insight into the effects of racism on the victims of it, on those who practice it, and the effects on American society. The effects of racism on the victims differed depending on age and whether or not a person would withstand the abuse. Moody makes these connections in her book by realizing that when the civil rights movement picked up in the 1960s, older blacks usually remained nonoperational and never stood up for themselves by speaking out against the abuse they received. In contrast, younger black Americans, notably teenagers, were more likely to be fearless and contemplate part in the Movement. This theme can be seen throughout the whole book, from when Anne was a young girl and never understood why her mother co... ...any whites could leave believed so strongly that blacks were inferior to them, so mediocre that they would treat them like animals and murder them in cold blood. But this is a problem that still occurs today, though in a lesser form, and it is important to study our past in effort to keep from repeating the mistakes of our ancestors. By reading things such as Anne Moodys autobiography, we can get an inside view into what really took place in the South, and we can be inspired by people like Moody who stood up to it. The negativities of racism against blacks taught us important lessons about ethics and how humans should treat each other because we can see the effects it had on people less than 50 years ago. And if we learn from the mistakes of our ancestors and move away from their supremacist ideals, then as the freedom song in Coming of Age goes, we shall overcome.

Gun Control Essay -- Second Amendment The Right To Bear Arms

A well-regulated militia, being necessary to the security of a free state, the right of the people to keep and bear arms, shall not be infringed. Does our second amendment really give rights to civilians to carry guns, which are a mechanical device that expels a bullet which can accurately travel great distances? As the U.S. sees it today, guns are legal to anyone who fits their criteria. Guns have been used for hundreds of years in the history of our world and nation. However, gun condition has been a major debating issue during the previous(prenominal) few decades. On one side, there are those who completely agree with the control laws and on the other there are those who oppose gun control laws all together. Gun control opponents provide many justifications for carrying a gun, such as the second amendment, self-defense, hunting, or target practice.Guns are not for everyone. Certain individuals cannot allot a firearm safely, and most individuals choose to use firearms unsuitab ly. Our society has passed laws regulating the possession and use of firearms, and more legislation is being considered. Most of this legislation restricts, to some degree, the rights of individuals to possess or use firearms. Some limitations may be necessary, but some modern legislation has gone too far. Society benefits from firearms in the custody of conscientious citizens. Attempts to keep firearms away from these citizens do more harm than good. (stated by the NRA)...

Understanding Eskimo Science :: essays research papers

In Richard Nelsons Understanding Eskimo Science a man, Nelson, traveled below the Arctic Circle in the boreal forest of internal Alaska were he lived, studied and interacted with a few native Eskimos groups during the mid-1960s. Through bulge the oblige Nelson provides an abundance of interesting and relevant information astir(predicate) Eskimo survival coming about through the understanding of ones environment. Nelsons best argument is the simple fact that these people have managed to survive in one the, if non the, harshest environment on the planet. There knowledge is useful, tested and true to the groups as this truly unique understanding of there world has permitted them to thrive well in these parts. Although the vegetation is rather scarce the Eskimos made due with a diet based mostly on hunting. But as we find out in the article Nelson describes how these people are well adapted to the art of hunting. The relationship betwixt man and animal is described to be one of en tangled understanding and respect Koyukon hunters know that an animals life ebbs slowly, that it remains aware and sensitive to how people treat itsbody. The Eskimo people have stash away a massive memory based archive of scientifically valid knowledge concerning the diverse workings of the landscape of Alaska. Unfortunately Nelson makes it all too form that this knowledge is disappearing and he fears that once gone there will never again be such a deep link between man and land. On a side note, this arcticle also makes it clear that the Eskimos respect there elders and place them at the head of all that is important as there knowledge and experience is treasured. They are the teachers of there people and the identity of the Eskimo is reflected in stores of experience in the minds of elders like Igruk. Nelson is most obviously a shrewd man saying rational things, but as is often the case with topics concerning native people, this knowledge will probably be lost in time. This arti cle makes one think about man as a hole. Are we truly happy in our jungles of steel? Have we not lost something of spectacular importance, something the Eskimo people have managed to conserve through all these millennia. We have lost contact with the spirit of nature. We have lost it to a point where our scientist do not consider Eskimo science (general knowledge) as a valid enough foundation for

The Morally Good and Bad in Othello Essays -- Othello essays

The Morally Good and Bad in Othello William Shakespeares maneuver Othello is one concentrated contest between the forces of the morally good and the morally bad. Let us analyze this contest in detail in this essay. standing(a) out like a dark silhouette on a white background is the sinister character and master of deception in the maneuver the generals ancient. Morton W. Bloomfield and Robert C. Elliott in Great Plays Sophocles to Brecht highlight the dominant evil force in the play, Iago For critics, the chief problem in the play is the character of Iago. The palisade usually centers around whether he had sufficient motives for his cruel actions or whether, on the other hand, he is an example of motiveless malignity. The question cannot be resolved here, nor is it necessary to try to resolve it. Iago, whether because of his disappointment at not having been given Cassios position, or because of his belief that Othello had cuckolded him, or because of his love of evil for i ts own sake, is nevertheless a man who has rejected all ties of morality and idealism. (39) Totaling the lies which the ancient tells to everyone about him would require considerable effort and time. In Shakespeares Four Giants Blanche Coles comments on the lack of frankness in Iagos speech The story that Iago tells Roderigo about the promotion of Cassio over him is not true, although it has been accepted by many discriminating scholars. Careless reading all can account for this misapprehension, careless reading which for the moment dulls their alertness to one of the most essential requirements of Shakespearean character analysis. That requirement is that the reader must never accept, or must always be re... ...is final passion.
